Banquet photography was alive and well in the communist culture - endless pictures of delegates to 12th Plenary Session of the 17th Party Congress and other hit images. I suppose it is an advantage to one party rule: you can get all the politicos to stand still in one group for a portrait. I imagine banquet photography is still practiced in Cuba and N. Korea.
